I have been walked through three phases about deciding whether I need Facebook or not.
The first phrase is to upvote it when I was young and the social media is fresh which made you think you need it because everyone had it and used it. You would be uncool if you don't have one. And I could interact with my friends and "participate in their lives even though I was so nerd then. Also, the newsfeed kept me staying in trend (I thought so).
The second phrase is complicated. I wanted to devote it when I was trying to keep life simple. My mind was distracted all the time and thus I did not have enough sleep. And I want to installed it back when I need positive stress to push myself after seeing my friend's successes on Facebook and Instagram, too.
And the third phase, which is happening, I don't really care about it despite the Delete Facebook movement due to the massive data breach, expert's urges to run away from social media, or scandals about how politicians took advantage of it because I have been grown up. Facebook is just a tool and it is not the culprit to make my life messy. It is my mind that have been controlling my behavior. Now I barely share my life on it since my boss and my colleagues could see it. I want to have my private life back.
If I have to decide whether I prefer my life without Facebook, I would say no, because it is just a tool. Don't think over it.
